This value represents the compiler version. It does not provide "backward" compatibility since it is a GUID. It is meant to capture the state of the translator/VM compiler structure and force a flush of any files in the DDC. Since it is a GUID, we don't need to worry about multiple people editing the translator having conflicting files in the shared DDC as there should never be any collisions.
